许多甲藻的生活史包括至少一个无鞭毛的底栖阶段（孢囊）。在文献中，不同类型的甲藻孢囊主要根据形态（细胞壁中的层的数量和类型）和功能（长期或短期耐力）差异来定义。这些特征最初被认为是明确区分表膜（薄壁）孢囊从休息（双壁）甲藻孢囊。前者被认为是短期的（暂时的），后者是长期的（静止的）囊肿。然而，在过去的二十年里，进一步的知识突出了甲藻生活史的巨大复杂性，包囊阶段的生态意义，以及需要澄清不同包囊类型的功能和形态的复杂性。在这里，我们回顾，并在必要时，重新定义的概念休息和表膜孢囊，检查其结构和功能特性的背景下，几个甲藻物种的生活周期策略。
The life cycle of many dinoflagellates includes at least one nonflagellated benthic stage (cyst). In the literature, the different types of dinoflagellate cysts are mainly defined based on morphological (number and type of layers in the cell wall) and functional (long- or short-term endurance) differences. These characteristics were initially thought to clearly distinguish pellicle (thin-walled) cysts from resting (double-walled) dinoflagellate cysts. The former were considered short-term (temporal) and the latter long-term (resting) cysts. However, during the last two decades further knowledge has highlighted the great intricacy of dinoflagellate life histories, the ecological significance of cyst stages, and the need to clarify the functional and morphological complexities of the different cyst types. Here we review and, when necessary, redefine the concepts of resting and pellicle cysts, examining both their structural and their functional characteristics in the context of the life cycle strategies of several dinoflagellate species.
